SEM_APIS.GET_INC_INF_INFO

Format

SEM_APIS.GET_INC_INF_INFO(
     entailment_name     IN VARCHAR2,
     enabled             OUT BOOLEAN,
     prev_inf_start_time OUT TIMESTAMP,
     network_owner       IN VARCHAR2 DEFAULT NULL,
     network_name        IN VARCHAR2 DEFAULT NULL);

Description

Returns incremental inference information for an entailment.

Parameters

entailment_name

Name of the entailment.

enabled

Boolean value returned by the procedure: TRUE if incremental inference is enabled for the entailment, or FALSE if incremental inference is not enabled for the entailment.

prev_inf_start_time

Timestamp indicating when the entailment was most recently updated (if incremental inference is enabled).

network_owner

Owner of the RDF network. (See Table: network_owner and network_name Parameters.)

network_name

Name of the RDF network. (See Table: network_owner and network_name Parameters.)

Usage Notes

To enable incremental inference for an entailment, use the SEM_APIS.ENABLE_INC_INFERENCE procedure.

For an explanation of incremental inference, including usage information, see Performing Incremental Inference.

For information about RDF network types and options, see RDF Networks.

Examples

The following example displays incremental inference information for an entailment.

DECLARE
  bEnabled boolean;
  tsEnabled timestamp;

DECLARE
  EXECUTE IMMEDIATE 'create table m1 (t SDO_RDF_TRIPLE_S)';
  sem_apis.create_sem_model('m1','m1','t');

  sem_apis.create_entailment('m1_inf',sem_models('m1'),
sem_rulebases('owlprime'),null,null,'INC=T');

  sem_apis.get_inc_inf_info('m1_inf', bEnabled,  tsEnabled);
  dbms_output.put_line('is enabled:' || case when bEnabled then 'true' else 'false'
  end);
  dbms_output.put_line('enabled at:' || tsEnabled);
END
